JOHN JOSEPH HICKEY, OF NEW YORK, N. Y.

DRIP-WATER SAFE.

To all whom it may concern:

Be it known that I, J OHN Josnrn HIcKEY, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Dripater Safe, of which the following is a full, clear, and exact description.

This invention relates to sanitary engineering and has particular reference to improvements in plumbing apparatus associated particularly with ice boxes, refrigerators or the like for private residences or apartment houses.

Among the objects of the invention is to provide a drip water reservoir or safe for refrigerators which is of the simplest possible nature but which is well adapted to meet the building regulations of our largest cities.

Another object of this invention is to pro vide a safe which may be easily applied to 0r removed from the main waste pipe by anyone who is skilled or unskilled and without the use of tools.

A further object of this invention is to provide a safe of the character set forth which is composed of the least number of parts and which may be easily kept clean.

The foregoing and other objects of this invention will hereinafter be more fully described and claimed and illustrated in the drawings forming a part of this specification in which like characters of reference indicate corresponding parts in all the views, and in which Figure 1 is a diagram indicating the location and use of this particular invention in relation to a refrigerator and the main waste pipe of an apartment house; Fig. 2 is a vertical sectional view of a preferred form of the safe complete; Fig. 3 is a fragmentary plan view of the same; Fig. 4 is a plan view of the center of the device with the dome and screen removed; and Fig. 5 is a detail of the bushing constituting a fixed attachment to the funnel,

The several parts of the device may be made of any suitable materials, and the relative sizes and proportions, as well as the general design of the mechanism, may be varied to a considerable extent without departing from the spirit of the invention hereinafter more fully set forth and specifically claimed. 7

This invention as a whole is indicated by Specification of Letters Patent.

the numeral 10 and connected through an elbow connection 11 to the main standard waste water pipe 12 which will be understood as extending in any way through or along all of the floors of a building. The lower end of this water from all of the safes into a trap arranged ordinarily in the basement of the building, the same trap serving for all of the apartments tributary to this particular 1pc. P The invention proper comprises a funnel. 13 shown as substantially circular and having an inclined bottom leading toward the bushing 14 secured to and extending downwardly from said bottom. includes a marginal upstanding flange or rim 15. The funnel is made preferably of cast iron or other metal of a strong and reliable nature, and the bushing 14 is preferably secured thereto in a peculiar manner during the casting operation. As shown in Fig. 2, the bushing is provided with interior and exterior threads 14 and 14 respectively, both threads being preferably of right hand type and extendin throughout the length of the bushing. W ithout being limited to any particular dimensions, I may say, by way of illustration, that the bushings in practice are usually about an inch in length and of a diameter to fit waste Water pipes of either one and a quarter inches or one and a half inches in diameter, the smaller pipe being connected to the inner thread of the bushing and the larger pipe being connected on the outside.

In addition to the threading of the bushing it vis formed at one end with one or more notches 14* which intersect one or more of the first turns of the thread 14: at the end where the connection is made with the bottom of the funnel. In making the casting the bushing is put in place in the mold and the metal poured so as to flow around the upper edge of the same, filling the notches 141 and the adjacent portion of the thread 14", though leaving the lower end of the thread 14 exposed. This particular manner of securing the bushing to the funnel is of a very simple and cheap nature and makes a reliable connection for the reason that the casting metal which enters the notches serves as keys preventing relative rotation between the funnel and bushing, making it impossible for the bushing to be unscrewed from the funnel, and the interpipe delivers the drip The funnel also adjacent the flange or locking engagement between the cast metal 'vanized.

and the thread prevents any possibility of lengthwise displacement of the bushii'ig.

The inner thread 14: of the bushing provides not only a means for the connection of the safe to a small waste pipe, but constitutes a seat at its upper end for a removable dome 16 having a thread at its lower end cooperating with the thread l-l. Said dome is of peculiar construction, being formed at its bottom with a pair of circumferentially arranged slots 16 through which the drip water or the most of it passes into and through the bushing. The dome also is provided with any suitable number of other openings 16 extending" radially through the shell thereof and at its top it is formed with a larger opening 17 constituting a standing overflow for the purpose of safety. The top of the dome lies below the plane of the upper edge of the flange 15 and hence, if any of the side openings of the dome should become clogged, the water will certainly flow through the opening 17 before flooding the floor of the apartment.

To facilitate the cleansing of the safe because of accumulation of mud, slime or the like, I. employ a screen 18 substantially diskshaped and provided with numerous holes 18 through which the drip water ordinarily passes. The screen being fiat is supported at its periphery upon. the bottom of the funnel rim 15 and hence spaced from the central portion of the funnel bottom, as shown especially in Fig. 2. The disk also is formed with a large central hole 18 where it surrounds the dome below the top thereof.

The main water pipe with its elbow extensions being put in place by the builder and plumber, each safe may be easily put in place simply by screwing it to the upstanding section of its elbow connection, sufficient power for this purpose being had by grasping the flange portion thereof. ()rdinarily the funnel will then remain in place. No water can leak through between the bottom of the funnel and the bushing because the cast metal in cooling shrinks snugly upon the end of the bushing and for the further reason that these devices are ordinarily gal- The dome may easily be screwed "u place by hand, not requiring any special power for this purpose, the joint not being required to be watertight. The disk screen also slips into or out of place easily.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The herein described drip water safe comprising a cast metal funnel having a permane ntly attached bushing, said bushing being threaded throughout its length inside and outside and formed at its upper end with one or more notches intersecting the outer thread, the cast metal entering said notches and forming locking means to prevent relative rotation between the bushing and the funnel, said bushing being adapted to be secured to different sizes of waste wa- 7 O tor elbow connections, and a dome removably connected by a screw thread to the upper end of the inner bushing thread.

2. in a drip water safe for waste water pipes, the combination of a cast metal funnel having an upwardly projecting cylindrical flange and a downwardly projecting internally and externally threaded bushing, said bushing being secured to the funnel during the casting thereof, a dome having threaded engagement at its lower end with the upper end of the inner bushing thread, said dome being provided with one or more slots circumferentially arranged around the bottom thereof and also being provided with safety overflow openings along its sides and top, the top of the dome being below the upper edge of the flange aforesaid, and a fiat perforated plate surrounding the dome within the flange and supported upon the bottom of the funnel adjacent the flange, the central portion of the plate being spaced from the central portion of the funnel, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
